Legrand 3P Fuse Switch Disconnector 10A D01 model 606703 (3-pole, 10 A)

The Legrand 3P Fuse Switch Disconnector 10A D01 model is a three-pole device designed to combine switching and overcurrent protection in a compact assembly. It accepts D01-size fuses and provides both isolation and fault protection for low-current circuits in residential and light commercial electrical installations. The unit enables safe disconnection of three-phase or multi-conductor circuits for maintenance and replacement of fuses while offering a clear mechanical open/closed indication.

Advantages

This 3-pole fuse switch disconnector integrates switching and fuse protection in a single module, reducing panel space and simplifying wiring. Its compatibility with standard D01 fuses makes replacement straightforward and widely supported. The device provides positive isolation for safe maintenance operations and contributes to improved circuit protection management. The compact design is suited to distribution boards where three-pole protection is required without large physical footprint.

Suitable for

• Three-phase supply isolation and protection in residential electrical panels
• Protecting motor feeds and small distribution circuits up to 10 A
• Maintenance isolation for downstream equipment and circuit servicing
• Light commercial installations requiring coordinated overcurrent protection

Key specifications

• Poles: 3 (three-pole switching and protection)
• Rated current: 10 A
• Compatible fuse size: D01
• Function: Combined switch and fuse disconnector for isolation and overcurrent protection
• Mounting: Panel/metering board installation (DIN rail or panel cut-out depending on installation practice)

How to use

Install the unit in the distribution board in accordance with local electrical codes and Legrand installation guidelines. Fit appropriate D01 fuses rated for the circuit and rated current, then connect line and load conductors to the designated terminals, ensuring secure tightening of terminals and correct phase ordering for three-pole circuits. Use the switch handle to isolate the circuit before performing maintenance or replacing fuses; verify absence of voltage with suitable test equipment before touching conductors. Ensure proper torque on terminal screws and verify that the enclosure and wiring provide required protective separation.

Usage recommendations

Use D01 fuses with appropriate time-current characteristics for the protected load and ensure coordinated protection with upstream devices. Regularly inspect the switch for signs of overheating, discoloration or loose connections and replace fuses only when the device is in the open position and the circuit is confirmed de-energized.
